Although the direct cytotoxic effects of high cellular GSSG levels have been documented in a variety of cell types 33,34,35,36 , our cell culture studies with hepatocytes revealed that increased GSSG accumulation, despite being non-toxic per se, could sensitize hepatocytes to TNF-induced killing, suggesting that GSSG and TNF can synergistically induce hepatocyte death and that GSSG-triggered sensitization to TNF hepatotoxicity represents a clinically relevant process that may account for disease progression in NAFLD
This loop swings the persulfide from the NFS1 active site to the scaffold protein, ISCU2, where it is transferred onto a specific cysteine on ISCU2
